Elastic Potential Energy Concepts

What is elastic potential energy?

• Energy stored in objects when they are stretched or compressed

• Energy stored in objects due to their height above the ground

• Energy stored in chemical bonds of molecules

• Energy stored in moving objects

Which of the following factors affect the amount of elastic potential energy stored in an object?

• Stiffness of the object and degree of stretching or compression

• Mass of the object and its velocity

• Temperature of the object and its material

• Shape of the object and its color

What happens to the elastic potential energy when a stretched object returns to its original shape?

• It is converted into kinetic energy

• It is destroyed

• It remains stored in the object

• It turns into thermal energy

Which of the following is an example of elastic potential energy in everyday life?

• A stretched rubber band

• A rolling ball

• A lit candle

• A flying bird

How do shock absorbers in vehicles utilize elastic potential energy?

• By using springs to store and release energy to manage impacts

• By converting elastic energy into electrical energy

• By using magnets to repel vibrations

• By absorbing heat from the surroundings
